Let present age of A = a, B = b, C = c According to question, => a - 10 = b - 6 => b = a - 4 Age of C after 7 years, => c + 7 = 20 Present age of C = 20 - 7 = 13 Total age of them = 25 × 3 = 75 years Now, a + (a - 4) + 13 = 75 => 2a - 4 = 62 => a = 33 years Required sum = (33 - 3) + (13 - 3) = 40 years
